'Gasland' sequel coming to HBO

Director Josh Fox lands deal with network to premiere next film in what could become a trilogy of documentaries on the natural gas industry.

Director Josh Fox may have lost out on an Oscar for his award-winning documentary, "Gasland," but that's not stopping him from continuing his fight against an industry he perceives as harmful to people and the environment.

"This is an emergency," Fox told the site. "The water supply for millions is at risk."

Mark Ruffalo, the most famous name attached to anti-fracking activism, is also ramping up his efforts by partnering with Fox on a summer/fall concert series through his new Water Defense initiative. The hope is to raise awareness of the dangers of fracking on both the environment and in drinking water.

“Water is our most treasured resource, it’s the most basic element of life and not having access to clean and safe water changes everything,” said Ruffalo in a statement. “Look at the people of Dimock, Penn.; Pavillion, Wyo.; and Silt, Colo., and so on who can’t use the water coming out of their faucets and need to have their water delivered by a tractor trailer from miles away — that’s us. This is our America, and we’re not going to just let that continue to happen.”
